Titre : Heritability, stability, and prevalence of tonic and phasic irritability as indicators of disruptive mood dysregulation disorder Type de document : Texte imprimé et/ou numérique Auteurs : A. A. MOORE, Auteur ; D. M. LAPATO, Auteur ; Melissa A. BROTMAN, Auteur ; E. LEIBENLUFT, Auteur ; S. H. AGGEN, Auteur ; J. M. HETTEMA, Auteur ; T. P. YORK, Auteur ; J. L. SILBERG, Auteur ; R. ROBERSON-NAY, Auteur Article en page(s) : p.1032-1041 Langues : Anglais (eng) Mots-clés : Disruptive behavior emotional dysregulation heritability mood disorder twins Index. décimale : PER Périodiques Résumé : BACKGROUND: Little is known about genetic and environmental influences on the components of disruptive mood dysregulation disorder (DMDD), tonic irritability (i.e., irritable mood) and phasic irritability (i.e., temper outbursts). This study examined prevalence, stability, and heritability of tonic irritability, phasic irritability, and a DMDD proxy (pDMDD) based on DSM-5 criteria. METHODS: pDMDD was derived using data from clinical interviews of parents and their twins (N = 1,431 twin pairs), ages 8-17, participating in Waves 1 and 2 of the Virginia Twin Study of Adolescent Behavioral Development. Biometrical modeling was used to compare a common pathway model (CPM) and an independent pathway model (IPM), and heritability estimates were obtained for pDMDD using the symptoms of irritable mood (tonic irritability; DMDD Criterion D), intense temper outbursts (phasic irritability; DMDD Criterion A), and frequent temper outbursts (phasic irritability; DMDD Criterion C). RESULTS: Lifetime prevalence of pDMDD was 7.46%. The stability of DMDD symptoms and the pDMDD phenotype across approximately one year were moderate (.30-.69). A CPM was a better fit to the data than an IPM. Phasic irritability loaded strongly onto the pDMDD latent factor (.89-.96) whereas tonic irritability did not (.28). Genetic influences accounted for approximately 59% of the variance in the latent pDMDD phenotype, with the remaining 41% of the variance due to unique environmental effects. The heritability of tonic irritability (54%) was slightly lower than that of frequent and intense temper (components of phasic irritability; 61% and 63%, respectively). CONCLUSIONS: Compared to tonic irritability, phasic irritability appears to be slightly more stable and heritable, as well as a stronger indicator of the latent factor. Furthermore, environmental experiences appear to play a substantial role in the development of irritability and DMDD, and researchers should seek to elucidate these mechanisms in future work.

Titre : Mood and anxiety disorders in very preterm/very low–birth weight individuals from 6 to 26 years Type de document : Texte imprimé et/ou numérique Auteurs : Julia JAEKEL, Auteur ; Nicole BAUMANN, Auteur ; Peter BARTMANN, Auteur ; Dieter WOLKE, Auteur Article en page(s) : p.88-95 Langues : Anglais (eng) Mots-clés : Preterm birth clinical diagnoses anxiety disorder mood disorder social support protection Index. décimale : PER Périodiques Résumé : Background Very preterm (<32 weeks’ gestational age; VP) or very low–birth weight (<1,500 g; VLBW) birth has been associated with increased risk for anxiety and mood disorders and less partnering in adulthood. The aim was to test whether (a) VP/VLBW are at increased risk of any anxiety or mood disorders from 6 to 26 years compared with term-born individuals; (b) social support from romantic partners is associated with protection from anxiety and mood disorders; and (c) VP/VLBW adults’ lower social support mediates their risk for any anxiety and mood disorders. Methods Data are from a prospective geographically defined longitudinal whole-population study in South Bavaria (Germany). Two hundred VP/VLBW and 197 term individuals were studied from birth to adulthood. Anxiety and mood disorders were assessed at 6, 8, and 26 years with standardized diagnostic interviews and social support via self-report at age 26. Results At age 6, VP/VLBW children were not at increased risk of any anxiety or mood disorder. At age 8, VP/VLBW more often had any anxiety disorder than term comparisons (11.8% vs. 6.6%, OR = 2.10, 95% CI [1.08–4.10]). VP/VLBW adults had an increased risk for any mood (27.5% vs. 18.8%, OR = 1.65 [1.02–2.67]) but not for any anxiety disorder (33.0% vs. 28.4%, OR = 1.27 [0.82–1.96]). None of the significant differences survived correction for multiple testing. Social support was associated with a lower risk of anxiety or mood disorders in both groups (OR = 0.81 [0.68–0.96]) and mediated the association of VP/VLBW birth with any anxiety or any mood disorders at age 26. Conclusions This study does not show a persistently increased risk for any anxiety or mood disorder after VP/VLBW birth. Low social support from a romantic partner mediates the risk for anxiety or mood disorders after VP/VLBW birth.

Methods The Scottish Bipolar Family Study is a prospective longitudinal investigation examining young individuals (age 16–25) at familial risk of mood disorder. Participants underwent functional MRI using an implicit facial processing task employing angry and neutral faces. An explicit facial expression recognition task was completed outside the scanner. Clinical outcomes obtained 2 years after the scan were used to categorise participants into controls (n = 54), high-risk individuals who had developed MDD (HR MDD; n = 30) and high-risk individuals who remained well (HR Well, n = 43). Results All groups demonstrated activation patterns typically observed during facial processing, including activation of the amygdala, hippocampus, fusiform gyrus and middle frontal regions. Notably, the HR MDD group showed reduced activation of the anterior cingulate gyrus versus both the control and HR Well group for angry faces, and versus the HR Well group for neutral faces. Outside the scanner, the HR MDD group was less accurate in recognising fearful expressions than the HR Well group. Conclusions Here, we demonstrate functional abnormalities of the anterior cingulate cortex alongside facial emotional recognition deficits in high-risk individuals in the early stages of depression compared with both controls and at-risk individuals who remained well. These neural changes were associated with a current or future diagnosis of MDD and were not simply associated with increased familial risk.

Titre : Practitioner Review: Definition, recognition, and treatment challenges of irritability in young people Type de document : Texte imprimé et/ou numérique Auteurs : A. STRINGARIS, Auteur ; P. VIDAL-RIBAS, Auteur ; Melissa A. BROTMAN, Auteur ; E. LEIBENLUFT, Auteur Article en page(s) : p.721-739 Langues : Anglais (eng) Mots-clés : Emotional dysregulation assessment intervention mood disorder temper tantrums Index. décimale : PER Périodiques Résumé : BACKGROUND: Irritability is one of the most common reasons for referral to child and adolescent mental health services and is the main characteristic of the new diagnosis of disruptive mood dysregulation disorder (DMDD). However, the recognition and management of irritability presents a major challenge in clinical practice and may be partly responsible for the dramatic increase in antipsychotic prescribing in recent years. METHODS: In this review, we provide up-to-date information on the definition and mechanisms underlying irritability, and its assessment in clinical practice. We aim to discuss the latest research on DMDD, and the presence of severe irritability in the context of other disorders, as well as to recommend a treatment algorithm. RESULTS: Severe irritability is associated with aberrant reward processing and bias toward threatening stimuli. Several measures are available to easily assess irritability. The recent diagnosis of DMDD captures children whose main problem is severe irritability and differ from those with bipolar disorder in longitudinal outcomes, family history, and behavioral and neural correlates. Treatment of irritability might depend on the context it appears. Indirect evidence suggests that parent management training (PMT) and cognitive behavioral therapy (CBT) are the most supported psychological treatments for irritability. CONCLUSIONS: Irritability, recognized as a mood problem rather than a purely behavioral manifestation, is a common condition for young people. Practitioners should not ignore irritability as it is associated with substantial morbidity and impairment. Although there are no trials with irritability as main outcome, clinicians can apply several existing pharmacological and psychological interventions for its treatment. Also, new promising approaches relying on pathophysiological findings, such as exposure-based cognitive behavioral therapy techniques and interpretation bias training (IBT), are being currently investigated.
